What is Vitamin D Good For? (Part 1: Musculoskeletal System) Vitamin D is needed by virtually every cell in the body and is essential for the proper function of hundreds of physiological processes

Lately we have been focusing much of our attention on vitamin D and its role in immune health. However, vitamin D is used by virtually every cell in the body and contributes to hundreds of physiological processes for a wide array of health effects. Vitamin D, by turning genes on or off, acts as a protector and regulator so it is able to enhance the functioning of cells, tissues and organs to keep us healthy and defend against disease. From musculoskeletal to cognitive and mental-emotional wellness, vitamin D has many benefits, and a deficit in vitamin D can lead to impairment or disease. With this in mind, why take a chance at being deficient in vitamin D?

Today’s post on vitamin D in the musculoskeletal system is the beginning of a series that will take it back to the basics – to review the various roles of vitamin D and why getting enough is important to many aspects of our physical and mental health.

Your Bones & Muscles Need Vitamin D

Vitamin D gained much attention in the early 1900s due to its role in the prevention of rickets. Rickets is a disease originally discovered when a lack of sunlight (resulting in a lack of vitamin D production) led to the softening and weakening of developing bones in young children, as people moved from farms to the cities. Children with vitamin D levels less than 20 ng/ml (50 nmol/L) are at risk for rickets, and it is a problem still to this day.

Despite the fact that a vitamin D level of 20 ng/ml is enough to prevent most cases of rickets in children, it may not be enough for other musculoskeletal benefits, as vitamin D also:

  • Influences calcium and magnesium concentrations – both important co-nutrients for muscle and bone development and function
  • Directly stimulates bone mineralization throughout life
  • Improves skeletal muscle function, normal coordination and balance
  • Rebuilds skeletal muscle tissue and reduces inflammation, such as after high impact exercise or injury

Musculoskeletal disease associated with low vitamin D include:

How Much Vitamin D do Your Bones & Muscles Need?

Similar to our Disease Incidence Prevention chart, the table below, adapted from a paper Sports Health Benefits of Vitamin D by Shuler et al., illustrates the impact of different levels of vitamin D on multiple aspects of the musculoskeletal system. As mentioned above, up to 99% of rickets cases can be prevented at levels of 20 ng/ml (50 nmol/L), however, additional benefits for bone and muscle health can be seen with higher vitamin D levels. Studies have also shown that maintaining a vitamin D level of at least 40 ng/ml (100 nmol/L) resulted in a decreased risk of bone fracture and stress fracture. Fast-twitch muscle fibers have been shown to be especially sensitive to vitamin D levels, which are important for burst activities and fall avoidance. Overall, cumulative research has shown that peak musculoskeletal performance may occur with a vitamin D level of at least 50 ng/ml.

Other Important Co-Nutrients for Bones & Muscles

Don’t forget that vitamin D works along with other essential nutrients for our health. For bones and muscles, these include:

Are You Getting Enough Vitamin D to Support Healthy Bones & Muscles?

With almost 90% of the general population having vitamin D levels below the recommended 40-60 ng/ml (100-150 nmol/L), it is obvious that most people need more vitamin D. While most of us cannot achieve a vitamin D level of 40-60 ng/ml (100-150 nmol/L) from sun alone, either due to our lifestyle, where we live, or other circumstances, we can certainly reach those levels with the right amount of supplementation.

What amount is right for you? The only way to tell is to test your level of vitamin D – from there, use the vitamin D*calculator to help you determine a dose of vitamin D to achieve your desired target level, and choose either a regular daily maintenance dose (to reach your goal in approximately 3 months), or start with an initial “loading dose” to help bump it up more quickly (loading doses do not go above 25,000 IU per day, which is the amount our bodies can produce from proper sun exposure, and can help us reach our target level within only weeks).

What does the Research Say about Vitamin D & COVID-19?

It’s TIME to start saving lives! If you can help PREVENT the majority of the death, it’s time! What’s it costing you/us not to take action NOW?

There is much published research that supports a clear link between vitamin D and COVID-19 showing that higher vitamin D levels are related to:

a decreased risk of testing positive for COVID-19

increased viral SARS-CoV-2 RNA clearance

better clinical outcomes among patients with COVID-19

less severe COVID-19 disease

decreased risk of death due to COVID-19

Be sure to educate yourself on the benefits and importance of vitamin D for immune health, and take steps to ensure you and your loved ones are getting enough.

You can review all of the COVID-19 and immune health information we have shared on this page.

What Does it Take YOU to Get Your D to 40 ng/ml (100 nmol/L)?

Did you know your health could be greatly affected by making sure you have a vitamin D level of at least 40 ng/ml (100 nmol/L)? Help us help you.

STEP 1 - Do you know what your vitamin D level is? If not, be sure to test today to find out.

STEP 2 – Determine your target level. Are you at your target level? Experts recommend a level of at least 40-60 ng/ml (100-150 nmol/L).

STEP 3 – Need to boost your level? Use the D*calculator to see how much vitamin D it may take to reach your target. Opt for the Loading Dose for a quicker boost.

STEP 4 – Optimize how your body absorbs and utilizes vitamin D with co-nutrients and these simple steps.

STEP 5 – Re-Test! This is an important step to make sure you have reached your target level, and to ensure you are not taking too much! Re-testing after 3-4 months is recommended.

STEP 6 – Adjust, Repeat…

Give your immune system the nutrients it needs to support a healthy you and protect yourself from unnecessary diseases, especially COVID-19.

NEWS ALERT

The first Randomized Controlled Trial on vitamin D and COVID-19 has shown a 96% lower risk of ICU admission for those receiving vitamin D (as 25(OH)D to quickly boost vitamin D blood levels) along with the standard treatment, compared to those receiving standard treatment alone.

These results support many previous observational studies showing a relationship between vitamin D levels and intake and COVID-19 severity.

Review the Latest Nutrient Research for COVID-19

GrassrootsHealth Nutrient Research Institute has launched the new Immune Boost project with the use of our myData-myAnswers nutrient health system that nearly 15,000 people are already using for their health. Specific markers that influence immune health are suggested for testing as part of this project including:

  • Vitamin D
  • Omega-3 Index
  • Essential elements magnesium, selenium, and zinc
  • hsCRP

Our goal is to demonstrate how one can use the Nutrient Research Model established by Dr. Robert Heaney to show the effect of vitamin D serum levels of at least 40 ng/ml (100 nmol/L) on risk reduction for all ethnicities in the population. Status and intake of other nutrients will also be analyzed for any type of relationship to immune status and symptom severity. Join the project today!
